Every American and multi-national corporation has adopted the position: race isn't genetic.

It flatters everyone to think we can all be whatever we want to be. Social mobility. If your grandparents were peasants, maybe you can be President. Hope, Change, Freedom, Justice, Equality, Liberty, Fraternity!

We also like to get ahead in social status by telling everyone they can be anything, and by helping those who cannot help themselves. These ineffective and inexpensive actions make us look good, even if we have to lie to do it.

African-American men with family histories of prostate cancer could benefit from a baseline prostate-specific antigen (PSA) reading to determine their probability of developing the disease.

The effect of the baseline PSA level on future prostate cancer risk was so robust that the correlation held true even for men with other significant risk factors.

Using a study cohort drawn from a longitudinal screening study enrolling more than 26,000 volunteers between 1991 and 2001, researchers analyzed a group of 329 African-American men with a family history of prostate cancer.

Eight percent of men in their 40s with both risk factors and a PSA above the median were diagnosed, as were 16 percent of men in their 50s. Twice as many men in their 60s with both risk factors and a baseline PSA above the median were diagnosed with prostate cancer.

Medical science treats all of these factors as important: race, age, PSA and risk-factors. African-Americans have more, different, and more pernicious cancers than white people.

At some point, we will grow up as a species and admit that evolution happened, and different groups going into different types of civilizations in different climates permitted genetic change -- or genetic adaptation. Africans, for example, are the most diverse; white people are the least diverse. But the specialized groups have genes adapted to deal with certain circumstances they encountered.

Our wise cohorts think that genetic engineering will be the future. But GM foods have worked so badly we're rethinking that. Race, like age and gender and other factors, is part of reality, and denying reality always ends badly.
